EXECUTE IMMEDIATE call to procedure

Question

need help on this piece of code.
1. lv_rec is a record of a table temp1 from which i need to validate lv_code.
2. The package1.proc_get_rec procedure has an IN OUT record parameter which is %ROWTYPE of the table in which the code exists.
3. lv_err_msg_out parameter will hold an error message if validation fails.
4. i need dynamic validation here because the table temp1(where code exists) and the package(needed to be called to validate the code) i am calling is residing in a defferent module.
declare
lv_plsql_block varchar2(1000);
lv_code :='B';
lv_rec temp1%ROWTYPE;
lv_err_msg_inout varchar2(100);
begin
lv_plsql_block := ' BEGIN package1.proc_get_rec(:1, :2, :3, :4); END;';
EXECUTE IMMEDIATE lv_plsql_block USING
lv_code,
SYSDATE,
IN OUT lv_rec,
IN OUT lv_err_msg_inout;
dbms_output.put_line('Err msg is '||lv_err_msg_inout);
end;
When i execute the above piece of code, i get the following error message:
Oracle Error :: PLS-00457 expressions have to be of SQL types
Is there any workaround for this problem??
Thanks in advance

Answer 1

There is a procedure proc_get_rec which uses a %ROWTYPE of a table.
This procedure and table temp1 might exist or might not exist in the database based on the type of installation of the product
Now I cannot directly execute the above procedure because the table temp1 might exist or not.
So I am using dynamic SQL to make sure that there are no compilation errors.
In Dynamic SQL I am not able to pass the %ROWTYPE parameter of the procedure dynamically.
Kindly suggest some workarround for this.
Below is the sample of the procedure through which the dynamic SQL is called:
procedure P1 (lv_code varchar2(10))
is
lv_plsql_block varchar2(1000);
lv_rec temp1%ROWTYPE;
lv_err_msg_inout varchar2(100);
begin
lv_plsql_block := ' BEGIN package1.proc_get_rec(:1, :2, :3, :4); END;';
EXECUTE IMMEDIATE lv_plsql_block USING
lv_code,
SYSDATE,
IN OUT lv_rec,
IN OUT lv_err_msg_inout;
dbms_output.put_line('Err msg is '||lv_err_msg_inout);
end P1;
